This is the first of an undetermined number of posts in a chair design series. My goal is to make a completely 3D printed, functional chair based on Enzo Mari’s chair from his book, Enzo Mari – autoprogettazione? My plan is to spend a fair amount of time designing the chair before I begin printing. I will be exploring ways to minimize elements while optimizing a design suitable for printing in a 600 cubic millimeter space. Instructional videos will be included. At the end, I should have a well-designed 3D printed chair and anyone participating should have one as well.
